For any surface of any lens, the profile curve length within theeffective half diameter affects the ability of the surface to correctaberration and differences between optical paths of light in differentfields of view. With longer profile curve length, the ability to correctaberration is better. However, the difficulty of manufacturing increasesas well. Therefore, the profile curve length within the effective halfdiameter of any surface of any lens has to be controlled. The ratiobetween the profile curve length (ARS) within the effective halfdiameter of one surface and the thickness (TP) of the lens, which thesurface belonged to, on the optical axis (i.e., ARS/TP) has to beparticularly controlled. For example, the profile curve length of themaximum effective half diameter of the object-side surface of the firstlens is denoted by ARS11, the thickness of the first lens on the opticalaxis is TP1, and the ratio between these two parameters is ARS11/TP1;the profile curve length of the maximum effective half diameter of theimage-side surface of the first lens is denoted by ARS12, and the ratiobetween ARS12 and TP1 is ARS12/TP1. The profile curve length of themaximum effective half diameter of the object-side surface of the secondlens is denoted by ARS21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARS21/TP2; the profile curve length of the maximum effective halfdiameter of the image-side surface of the second lens is denoted byARS22, and the ratio between ARS22 and TP2 is ARS22/TP2. For any surfaceof other lenses in the optical image capturing system, the ratio betweenthe profile curve length of the maximum effective half diameter thereofand the thickness of the lens which the surface belonged to is denotedin the same manner.

For any surface of any lens, the profile curve length within a half ofthe entrance pupil diameter (HEP) affects the ability of the surface tocorrect aberration and differences between optical paths of light indifferent fields of view. With longer profile curve length, the abilityto correct aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half of the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half of the entrance pupil diameter (HEP) of one surfaceand the thickness (TP) of the lens, which the surface belonged to, onthe optical axis (i.e., ARE/TP) has to be particularly controlled. Forexample, the profile curve length of a half of the entrance pupildiameter (HEP) of the object-side surface of the first lens is denotedby ARE11, the thickness of the first lens on the optical axis is TP1,and the ratio between these two parameters is ARE11/TP1; the profilecurve length of a half of the entrance pupil diameter (HEP) of theimage-side surface of the first lens is denoted by ARE12, and the ratiobetween ARE12 and TP1 is ARE12/TP1. The profile curve length of a halfof the entrance pupil diameter (HEP) of the object-side surface of thesecond lens is denoted by ARE21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARE21/TP2; the profile curve length of a half of the entrance pupildiameter (HEP) of the image-side surface of the second lens is denotedby ARE22, and the ratio between ARE22 and TP2 is ARE22/TP2. For anysurface of other lenses in the optical image capturing system, the ratiobetween the profile curve length of a half of the entrance pupildiameter (HEP) thereof and the thickness of the lens which the surfacebelonged to is denoted in the same manner.

In an embodiment, a height of the optical image capturing system (HOS)can be reduced while |f1|>f5.

In an embodiment, when |f2|+|f3|+|f4| and |f1|+|f5| of the lensessatisfy the aforementioned conditions, at least one lens among thesecond to the fourth lenses could have weak positive refractive power orweak negative refractive power. Herein the weak refractive power meansthe absolute value of the focal length of one specific lens is greaterthan 10. When at least one lens among the second to the fourth lenseshas weak positive refractive power, it may share the positive refractivepower of the first lens, and on the contrary, when at least one lensamong the second to the fourth lenses has weak negative refractivepower, it may fine turn and correct the aberration of the system.

In an embodiment, the fifth lens could have negative refractive power,and an image-side surface thereof is concave, it may reduce back focallength and size. Besides, the fifth lens can have at least an inflectionpoint on at least a surface thereof, which may reduce an incident angleof the light of an off-axis field of view and correct the aberration ofthe off-axis field of view.

In addition, the opposite surfaces (object-side surface andimage-side surface) of the first to the fifth lenses could be asphericthat can obtain more control parameters to reduce aberration. The numberof aspheric glass lenses could be less than the conventional sphericalglass lenses, which is helpful for reduction of the height of thesystem.

Sixth Embodiment

As shown in FIG. 6A and FIG. 6B, an optical image capturing system ofthe sixth embodiment of the present invention includes, along an opticalaxis from an object side to an image side, a first lens 610, a secondlens 620, an aperture 600, a third lens 630, a fourth lens 640, a fifthlens 650, an infrared rays filter 680, an image plane 690, and an imagesensor 692. FIG. 6C is a transverse aberration diagram at 0.7 field ofview of the sixth embodiment of the present application.

The first lens 610 has negative refractive power and is made of plastic.An object-side surface 612, which faces the object side, is a convexaspheric surface, and an image-side surface 614, which faces the imageside, is a concave aspheric surface. The object-side surface 612 and theimage-side surface 614 both have an inflection point.

The second lens 620 has positive refractive power and is made ofplastic. An object-side surface 622 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 624thereof, which faces the image side, is a convex aspheric surface. Theobject-side surface 622 has an inflection point.

The third lens 630 has positive refractive power and is made of plastic.An object-side surface 632, which faces the object side, is a convexaspheric surface, and an image-side surface 634, which faces the imageside, is a convex aspheric surface. The object-side surface 632 has aninflection point.

The fourth lens 640 has negative refractive power and is made ofplastic. An object-side surface 642, which faces the object side, is aconcave aspheric surface, and an image-side surface 644, which faces theimage side, is a convex aspheric surface. The object-side surface 642has two inflection points, and the image-side surface 644 has aninflection point.

The fifth lens 650 has positive refractive power and is made of plastic.An object-side surface 652, which faces the object side, is a convexsurface, and an image-side surface 654, which faces the image side, is aconcave surface. The object-side surface 652 has two inflection points,and the image-side surface 654 has an inflection point. It may help toshorten the back focal length to keep small in size. In addition, it mayreduce an incident angle of the light of an off-axis field of view andcorrect the aberration of the off-axis field of view.

The infrared rays filter 680 is made of glass and between the fifth lens650 and the image plane 690. The infrared rays filter 680 gives nocontribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies|f2|+|f3|+|f4|=8.4735 mm; |f1|+|f5|=8.9495 mm; and|f2|+|f3|+|f4|<|f1|+|f5|, where f2 is a focal length of the second lens620, f3 is a focal length of the third lens 630, f4 is a focal length ofthe fourth lens 640, and f5 is a focal length of the fifth lens 650.

In the sixth embodiment, the first lens 610, the third lens 630, and thefourth lenses 640 are positive lenses, and their focal lengths are f1,f3, and f4. The optical image capturing system of the sixth embodimentfurther satisfies ΣPP=11.46338 mm; and f3/ΣPP=0.15626, where ΣPP is asum of the focal lengths of each positive lens. It is helpful to sharethe positive refractive power of one single lens to other positivelenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the sixth embodiment furthersatisfies ΣNP=−5.95967 mm; and f1/ΣNP=0.56425, where ΣNP is a sum of thefocal lengths of each negative lens. It is helpful to share the negativerefractive power of one single lens to the other negative lens to avoidthe significant aberration caused by the incident rays.

The parameters of the lenses of the sixth embodiment are listed in Table11 and Table 12.
